Don't hesitate to contact us for latest COA and Test Report of Squalene
Squalene is used in cosmetics as a natural moisturizer. Squalene penetrates the skin quickly, does not leave a greasy feeling on the skin
and blends well with other oils and vitamins. Squalane is a saturated form of squalene in which the double bonds have been eliminated by
hydrogenation. Because squalane is less susceptible to oxidation than squalene, Squalene is more commonly used in personal care products.
Toxicology studies have determined that in the concentrations used in cosmetics, both squalene and squalane have low acute toxicity, and
are not significant human skin irritants or sensitizers.
